i paratus applied to it, and

` parts.

in the county of Albany, and State of New York, have invented a new and improved Binder for Lids of Gas' Retorts; and I do hereby declare thatthe following is a full, clear, and exact description thereof', which will enable others skilled lin theart to make and' use the 4 same, reference being had to the accompanying drawings, forming part ot' thisspeciication.

This invention relates to improvements in apparatus for securing the lids of gas-retorts, designed to provide a simple and elicient clamping-apparatus, which may be conveniently operated for opening and closing the retorte.

It consists in an arrangement of clam-pingdevers, supported in arms projecting fromv lugs formed upon thev retort, near the month, as hereinafter more fully Figure 1 represents a `horizontal section of a part of i a retort and lid, showing my improved clamping-api Figure 2 represents a'front elevation of the same.

Similar letters of reference indicate corresponding A represents the mouth of `a retort, which, according tomy improvement, is provided with slotted lugs B, preferably cast thereon, in which the arms `C D are anang'ed'to project from the front thereof. "1V The arm G isslotted at E, and a link, F, jointed to it at the outer end. Y

G yrepresents a lever, haviuga hooked end, for en- This lever extends to about the centre of the front of theretort, when adj usted to the position for clamping the cover thereto, and supports thereat the end of a cam-lever, K, the free end of which is provided with a spring-pawl, arranged to engage in a series of notches in the arm D.

The lid of the retort is cast with 'lugs L, for supporting it on the arms D C, in front of the retort.

It is also provided with a boss in the centre, against which the ciankfbears, when the lever thereof is pressed iuward and secured by the spring-pawl, thereby clamping the lid to the retort.

To remove the lid, the pawl is disengaged, and the cam-lever swung outward, to relieve the pressure of thecam on the lid.

This will 4permit the hook-headed lever G to be disengaged from the slot in` the arm C, and both the levers G and K to be swung' aronndon the link F and arm O, away from the lid, permitting'the ready removal thereof.

Having thus ydescribed my invention,

I claim as new, and desire to secure by Letters l PatentrlJhe combination, with'the retort, ofthe arms C D, link F, levers Gr K, all arranged substantially as speci-
